—This paper describes a framework for animating and controlling articulated bodies in a fluid simulation. We illustrate this approach by simulating an autonomous fish in various situations. Our little animal tries to reach a goal while its movement interacts with the fluid. Several algorithms allow the fish to automatically control its locomotion while taking into account the changing fluid for...

The entry of projectiles into water has been interest to many scientists and engineers, being crucial a wide range engineering applications. problem is nonlinear unsteady phenomenon involving complicated multi-phase flow problems fluid–solid interaction. Many have studying in various conditions through experimental methods numerical methods. In this paper, three-dimensional simulations the are ...

The flow-induced translocation of polymer chains through a microfluidic channel is investigated using particle-based Dissipative Particle Dynamics and modified Langevin Dynamics approaches. Adaptive noslip wall boundary conditions have been implemented to model fluid flow in the microfluidic channel, paying attention to controlling fluid density fluctuations. By varying the magnitude of the ext...

Due to the inhalation of airborne particles containing bacterial lipopolysaccharide (LPS), these molecules might incorporate into the 1,2-dipalmitoylphosphatidylcholine (DPPC)-rich monolayer and interact with surfactant protein A (SP-A), the major surfactant protein component involved in host defense. In this study, epifluorescence microscopy combined with a surface balance was used to examine ...

This work presents the eigenfrequencies of a study on fluid-structure interaction for pipe with circular section, under pressure constraints in laminar, incompressible and irrotational flow, followed by comparison between stiffness coupling bar different geometric ratio Radius/Length; Radius/Thickness, as frequency identity industry. The realization this is to have better coupling, where we use...

• A numerical scheme is proposed for the direct simulation of complex solid-liquid-gas three-phase flows. coupled LBM-DEM model ensuring mass conservation proposed. The upward migration bubbles through a brine-filled sediment column successfully simulated at various conditions. Simulation results indicate three different flow regimes: connected finger flow, transition and dispersed bubbly flow....

Abstract At present, in the aspect of numerical simulation a cycloid pump, most researchers are based on CFD (computational fluid dynamics) to analyze pump under different operating conditions (such as speed, temperature), and performance FSI (fluid solid interactions) is rare. Firstly, model cycloidal established COMSOL. The results obtained by applying verified experiments. Then, flow rotatin...
